If one or more virtual machines do require consolidation, you can do it right away. With this selection displayed, system administrators can easily have a quick view of the virtual machines and identify if a virtual machine needs consolidation. Figure A below shows this option added to the list of virtual machines in a cluster. Within the vSphere Client, you can add a column to the view to display if the virtual machine needs to have consolidation performed.
This will enable future snapshots to be taken and ensure that disk usage as well as snapshot features are correct. In this technique, any snapshots that are disconnected from the virtual machine, or are otherwise in play on the disk for the virtual machine, are corrected. If there is any type of anomaly in the process, VMware has a remediation step for the virtual machine called snapshot consolidation. We also have to ensure that nothing goes wrong with a snapshot being taken or removed. It is important however, to ensure that snapshot usage stays in check. In fact, many technologies leverage virtual machine snapshots for things like backups. That being said, snapshots are a great technology for VMware virtual machines (as well as other hypervisor technologies). This can be compounded as an individual virtual machine can have multiple snapshots taken for different points in time. The largest consideration is to understand that they will cause increased disk usage and, if forgotten about and left open, they will degrade performance over time. If you use VMware snapshots, there are a number of considerations that go along with them. Rickatron shows a quick and easy way to see if consolidation is needed. Virtual machine snapshot consolidation can improve performance and correctly manage disk space. Easy check to see if a VM needs snapshot consolidation
